basic number theory facts for math competition (Berkeley mini Math Tournament)

Описание: This basic number theory question is from the Berkeley mini Math Tournament in 2021. It is a math competition for middle school students run by UC Berkeley students. Here we are finding the sum of 1/a where a is a factor of the number 360. Is there an easier way to do this instead of finding all the factors of 360, doing the reciprocals, and then adding them up? Of course, there is! And we will also talk about some facts about factors in this video!

👉 The fall BMT (Berkeley math tournament for high school students) will be held on UC Berkeley campus on Saturday 11/5/2022. If you are interested in participating in BMT or BmMT, please visit
